This is the 27" iMac logic board for the mid 2017 model only. This is the first generation that used the Kaby Lake range of processors. This Logic board has a 4.2GHz Intel Quad Core i7 Processor. There are four ram slots on the rear of the logic board which can take up to 64GB of PC4-19200 (2400MHz) DDR4 SO-DIMM modules. This logic board has an integrated graphics card, AMD Radeon 575 (EL PROA) with 4GB of dedicated GDDR5 VRAM. This logic board has an 8.0 GT/s PCIe x4 port located on the rear of the logic board for a single modular SSD. This is the first range of iMac to have two Thunderbolt 3 (USB-C) ports capable of transferring data up to 40Gbps.
This is a highly static-sensitive device and replacement should not be attempted without suitable experience and anti-static precautions. If you remove the heat sink from the logic board, the seal must be re-made adequately when the new board is fitted to ensure the iMac does not overheat. Thermal paste is available from the Tools section.
Provided with 3month guarantee. No refund will be given for logic boards damaged during fitting.
